numpy.array_str¶

numpy.array_str(a,max_line_width=None,precision=None,suppress_small=None)[source]¶

Return a string representation of the data in an array.

The data in the array is returned as a single string. This function issimilar toarray_repr, the difference being thatarray_repr alsoreturns information on the kind of array and its data type.

Parameters:

a : ndarray Input array. max_line_width : int, optional Inserts newlines if text is longer thanmax_line_width. Thedefault is, indirectly, 75. precision : int, optional Floating point precision. Default is the current printing precision(usually 8), which can be altered usingset_printoptions. suppress_small : bool, optional Represent numbers “very close” to zero as zero; default is False.Very close is defined by precision: if the precision is 8, e.g.,numbers smaller (in absolute value) than 5e-9 are represented aszero.
